我正在處理一個 Django 項目，其中一個表單不會提交。我發現罪魁禍首是一些格式化貨幣輸入的 JavaScript（當我刪除 JS 或刪除輸入type="currency"時，它會提交）這是我的簡化形式 - JS 來自用于貨幣/貨幣的 html5 輸入var currencyInput = document.querySelector('input[type="currency"]')var currency = 'GBP'// format inital valueonBlur({  target: currencyInput})// bind event listenerscurrencyInput.addEventListener('focus', onFocus)currencyInput.addEventListener('blur', onBlur)function localStringToNumber(s) {  return Number(String(s).replace(/[^0-9.-]+/g, ""))}function onFocus(e) {  var value = e.target.value;  e.target.value = value ? localStringToNumber(value) : ''}function onBlur(e) {  var value = e.target.value  var options = {    maximumFractionDigits: 2,    currency: currency,    style: "currency",    currencyDisplay: "symbol"  }  e.target.value = value ?    localStringToNumber(value).toLocaleString(undefined, options) :    ''}<form action="{% url 'create_goal' %}" method="post">  <h4 class="mb-3" id="create">Create a Savings Goal</h4>  <input type="text" class="form-control" id="goalName" name="goalName" value="" required>  <input type="currency" min="0" pattern="^\d*(\.\d{0,2})?$" class="form-control" id="goal" name="goal" required>  <button type="submit" class="btn btn-secondary btn-block">Add Goal</button></form>
